    Synthesis of Isopentyl Acetate question

    Thank you chemisttree; your response was most lucid. Do you have any tips on how to increase yield in this experiment, or in orgo lab in general? I am often unable to remove all of the product from my flask during vacuum filtration, for instance.

    Synthesis of Isopentyl Acetate question

    Yes, water is a product, so the reaction is going to shift *left*, toward the reactants, which *lowers* the yield. Can someone please post what the extraction order should be?

    Creating a pH 6.7 Buffer Solution with Imidazole and C3H5N2Cl

    I have worked through the problem and spent quite a bit of time on it but am not extremely confident in my solution. I would just like someone to check my work. Cheers. Homework Statement -Need 0.4 L of an aqueous buffer solution of pH=6.7 -Have access to 0.02 M HCl, 0.02 M NaOH, 0.01 M...

    General Chemistry Pressure and Rate laws

    Thanks for your help. This is what I have done so far, but it is still wrong. ln[(PPH3)t / (PPH3)o] = -kt Ptotal = PPH3 + PP4 + PH2 PPH3 = Po - PP4 PH2 = 6PP4 Ptotal = (Po - PP4) + 6PP4 + PP4 Ptotal= Po + 6PP4 PP4 = (Ptotal - Po) / 6 PPH3 = Po -PP4 = Po - [(Ptotal-Po) / 6]...

    General Chemistry Pressure and Rate laws

    Homework Statement The kinetics of the decomposition of phosphine at 950 K 4PH3 (g) -> P4 (g) + 6H2 (g) was studied by injecting PH3(g) into a reaction vessel and measuring the total pressure at constant volume. P total (Torr) Time (s) 100 0 150 40...
